4 .16 The Security Code
The Security Code is the last step after setting all other
programming parameters for the Model 800. The code consists
of a 4-digit number you select and will effectively prevent
unauthorized changes to the Model 800’s programming. When
the Security Code is activated, all keyboard programming is
locked. The Model 800 may be interrogated using the WHAT IS
key, but the keyboard must be unlocked, via the Security Code,
before any programming changes are possible.
